Application filed June 23, 1915.

Z '0 all whom it may concern: 1 Be it known that l, JosnrH D. WILSON, a. citizen of the United States, residing at Stockton, in the county of Hunterdon and State of New Jersey, have invented new and useful improvements in Incubators, of which the following is a specification.

This invention relates to certain new and useful improvements in incubators.

The object of the invention is to provide an incubator with a hatching compartment having a heating means at the top thereof, a fabric bottom below the tray-and a sheet of loosely woven material abovethe egg tray, and to provide a valve for the top above the heating means which is operated by adiaphragm arranged in the compartment above the egg tray, and whereby a uni.- form amount of heat maybe at all times directed to the hatch ng com artment.

With the above and other objects inview, the improvement resides in the construction, c mbination and arrangement of partsset forth in the following specification andfalling within the scope of the appended claim.

In the drawings: Figure ,lis a top plan view of my improved incubator, parts being broken away, Fig. 2 is a longitudinal sectionalview approximately on the line22 of Fig. 1, Fig. 3 is a transverse sectional view approximately on the line 3-3 oflFig. 1, Fig. 4: is a similar-sectional view approximatch; on the line 47-42 of Fig. 1, 5 is an enlarged sectional view through the heater and the-controltherefor, Fig. 6 is'ra view takenwat right angles to that shown in Fig. 5, Figs'f'? and'S are details.

1n the accompanying drawings, the :body of the incubator is indicated by the numeral 1, the same being supported upon the usual legs 2. The body is divided into any num: ber of egg chambers 3 within which is dis posed upon suitable guidecleats the movable egg frames 4. Eachof the'chambers 3 is provided with a hinged door 5, which is normally retained in a closed position through a latch or look 5. Arranged" upon the bottom of each of the chambers 3 and forming a closure for the same is a frame 6, the said frame supporting a body ofthick fabric, preferably in the-nature. of felt, and which is indicated by the numeral 7. The felt is of course porous and permits of a certain inflow of cool air, but when the Specification of Letters Patent.

chamber isheated, in a manner which will presently be described, the entrance of cool air through the felt 7 will miX the heated air in the said chamber. Disposed a suitable distance below the top of the incubator and forming what may be termed the top of each of the chambers 3 is a strip of cloth 8, the same being preferably in the nature of burlap or'other loosely woven material so as to provide ascreen for permitting the free entrance of currents of heated air therethrough.

.Arranged within each of the chambers 3 Isa metallic diaphragm 9 for which iszpro' vlfcled asuitablepsupport 10, andthe diaphragmis provided with a rod 11 which passes through the-top of the incubator and whiohisconnected with arod or lever 12. This-lever: is provided with depending arms orflanges 13 which are pivotally secured to a stud let provideduprnthe top of the incubatOr andone-end of said rod 12 has ar ranged thereon an adjustable weight 15. :lhe rod 11 passesthrough a suitable openmg inthe lever and preferably. has its end threaded and engaged by .an interiorly threaded member 16, sothat the position of the diaphragm J9 upon its support 10 may be regulated. The rodl2ihas its. end opposite that provided with .the adjustable weight 1.5 hooked, as at 17, to engage with the bailor handle 18 of a'valve 20, the said valve?beingnormally rested. upon a seat 21,

the said seat being: preferably in the nature a of a tubular member which communicates with the interior of the incubator in thetop thereof andabove thescreen or. top'8'of'each of the chambers 3. It'will be apparent that when the diaphragm is properly adjusted and asufhcient heat passes through the porous top'8 of any of the chambers, the said heat will expand-the diaphragm, causing the same to swing the rod 12 and to open the valve 21, thus allowingra quantity ofheated air to pass through the top 8 of the chamber.

As stated, the bottom member 7 of each ofthe chambers is supported upon a frame 6, and this frame is slidable longitudinally of the incubator, so should occasion arise wherein it is found desirable that a greater quantity of cold airthan that normally ad- .mitted through the bottom 7 is required, any of the frames may be spread outwardly of the chamber, and this may prove desirable when eggs are arranged upon the frames 4 in certain cf the chambers and are not arranged upon the said frame in other of the chambers, so that non-occupied chambers may be thoroughlyventilated. Again,

it is to be understood that the partitions dividing the ob ambers extend above the members 8, which have been termed the top walls of the chambers and are connected directly to the top of the incubator, so it will be noted that there is no air communication between any of the chambers. Furthermore, these division members, which for distinction are indicated by the numerals 23, are so disposed that the edges of the adjacent doors'5 contact centrallv therewith.

Pcsitirned within one of the ends of the incubator are the heads of water circulating and heating pipes. The numeral 2% designates the lead pipe for the hot water,

7 the same projecting through the end of the incubator and having its inner end provided with a T from which extends branch pipes 2626, the said branch pipes being each connected with a longitudinally disposed water head 27-27, and extending longitudinally from each of the said heads are the hot water conducting pipes 22'. These pipes, as previously stated, are disptsed within the incubator between the top of the said incubator and the top 8 of the chambers 3 and pass through suitable openings in the partitions 23. The opposite end of each of the pipes 22 is provided with a U-bend 28 so that the return or cold water pipes 29 are arranged each intermediate of two of, the hot water pipes 22. The inner ends .of the return pines 28 are each provided with a vertical pipe extension 30, said pipes being connected with transverse head pipes 31,0ne of which being arranged below one of the head pi es or manifolds 27, and the manifolds 31 are provided with outlet pipes 32 which extend through the end of the casing, and said pipes may be conv nected and provided with'an outlet pipe 33.

The pipes 24 and 33 communicate with a. suitable furnace 34'which may be of any desired or preferred construction, such for in-' stance, as is illustrated in the drawings.

-' v The furnace 34- is provided with a top or -16'is hingedly connected with the top of the stove and is provided with a vertically extending rod 39. Said damper is preferably arranged opposite the stove pipe 40.

The numeral 41 designates a vertically disposed pipe connected with the pipe 33, the said. pipe communicating with a water receptacle 42 within which is arranged a ficat i3 having a vertically extending rod 44 which prcjects through the receptacle 4-2, said rod or stem 4:4: being connected with a lever i5 that is supported upon a suitable bracket 46 connected with the receptacle l2. The free end of the lever 4-5 has ccnnected thereto the end of the red 38. The rod 39 is also connected with the lever 47 and is suppcrted upon the vertical arm of a substantially L-shaned bracket 49, the said bracket reing adjustably secured upon the pipe ill, and the lever 47 is arranged at an angle to the le er 45 but underlies the outer end of the said lever 45. By an arrane'ement as above the compartments are heated to the required temperature and this temperature will be automatically maintained. The expansion of the liquid in the receptacle 4:2 will cause the Heat 43 to rise, and this, by reason of the connections described, will close the throttle 37 and open the damper 35 so that draft at the top of the furnace will be shut off, and at the same time the cold air draft is opened and cold air is ad mitted over the top of the fire pot and the liouid in the tank being cooled the float will fall and the throttle will open and the draft damper will be closed. The construction just described does not, however, form a part of this invention. but has been set forth at length in order to illustrate a satisfactory and practical means for regulating the temperature of the water passing through the heating'pipes for the several. chambers of my incubator.

Having thus described the invention,what I claim is:

In anincubator, a hatching compartment having heating means at the top thereof, a frame at the bottom of the compartment having a face of felt, an egg tray mounted on slides in the center of the compartment, a sheet of loosely woven material arranged horizontally in the compartment above the egg tray and below the heating means, a valved opening in the top of the compait, ment, and a diaphragm arranged in the C0111- partment below the loosely woven sheet and above the egg tray having a member connected therewith and with the valve.

In testimony whereof I atiix my signature in presence of two witnesses.
